eyust707 · Answer

thats the domain...

amistre64 · Answer

the domain given is discrete, not continuous ...

amistre64 · Answer

consider these in the format (D,R)

put all the D values together to form a domain

and all the R values together to form the range

amistre64 · Answer

any values that are repeated can be simplified to a single value

in this case:  R = {2,2,2,2} is "properly" written as R = {2}

do i multiply what?

anonymous · Answer

o_o this is confusing. I wish i could help! Sorry!

amistre64 · Answer

im sure i didnt mention anything about multiplying ....

amistre64 · Answer

collect your D values to define the domain; and your R values to define the range.

( D, R)
(-9, 2)
(-4, 2)
 (3, 2)
 (9, 2)

D = {-9,-4,3,9}

R = {2,2,2,2} = {2}
